BooK COVER.

applicati@ mea "september -To-'aZZ 'fwhom "it 77mg/ concern vrreI-I,IVAa citizen ofthe United States, and residentof the city-l of New York,in the county of lNew York and State of New v"York, have inventedcertain-new and'useful Improvements in Book Covers, of Iwhich thefollowing is -a' specification.

Thepresenttinventionrelates to book covers,-v oriinvr other words to`protecting Ameans placed outside the bodies of books andoverlying' thesame. j

lVhenbooksai-e subjected to hard usage, thefconnection'between the backs'and the sides of-thecoversthereof are usually iirst tosuffer.l'lhfisisduetothe fact that the connectionorA hinges, as theyaresometimes called, are, in -usinglthe book, frequently bent back Sandfforth, that is tosay -in opposite directions, and the connection is thusapt to be severed in time.

The main object of the invention is to provide a book cover, wherein theconnection between the back and the sides thereof is made of rubber orlike material, thereby withstanding hard usage.

A further object of the invention is to provide a book cover, all of theelements of which are made of rubber and united by vulcanizing action.

A further object of the invention is to provide the sides of a bookcover with inwardly projecting flanges, preferably, adjacent the freecorners thereof, thereby providing means for protecting the corners ofthe book.

A still further object of the invention is to produce corner protectorsof the type mentioned which are made integral with the sides of thecover.

With these and other' objects in view, which will more fully appear asthe nature of the invention is better understood, the same consists inthe combination, arranger nient and construction of parts hereinafterdescribed, pointed out in the appended claims and illustrated in theaccompanying drawings, it being understood that many changes may be madein the size and proportion of the several parts and details ofconstruction within the scope of the appended claims, without departingfrom the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of 4., 1924. `sei-m1 No. 735,838.

fthe invention is `illust-rated -in -the. accom- Be 1t known that I,Issmoma MRAGODANO- p anyin'g drawings, vin "which higure 1 1s a s1deelevation of a book cover constructedin accordance "'with'the present 'linvention Fi-g. 2` is an inner view not' the book'cover lnlitsopenposition; and

rig, e.,

In ithe-drawiii-gs, -t'he numerals 10 land respectively, of a ibookco`ver,-each ibeing of oblong configuration and compri-singla sheet --ofriibber of v-a suitable thicki'iess. The sheet-may' be "either soft orhard,-ac cord-ingfto the requirements, -t-and vis pro- `videdalong itsinner longitudinal `-edge with ya kerf 12 in lits inner face..Intothistkerfis littedone-fof'the longitudinal-edges of a,

preferal'ily, I soft rubber sheet zL13," which Acnstitutes the back ofthe cover. The elements are united by vuleanizing action in suitablemanner. To the inner face of the back may be secured in any suitablemanner, for instance by cement, a rigid oblong plate member 14, tostiften the back, if desired.

Each of the sides of the cover is provided along its free edges with aninwardly projecting flange 15, provided with notches 16 at suitableintervals, each of said notches being of a size to accommodate a fingerof the user. These flanges serve to protect the corners and edges of theleaves of th'e book. The height of each flange depends obviously uponthe thickness of the book it being, however, obvious that these iangesneed not Contact with one another when the book is in its closedposition. The anges may be provided only adjacent the corners of thebook, if desired, or they may be of a greater length according to therequirements. In the case illustrated, the flanges extend eachthroughout the length of a side of the book, but do not extendthroughout the widths thereof, as clearly shown in Figs. 1 and 3 of thedrawings.

It is obvious that, while herein the sides of the book have beendescribed as being made of rubber, they may be made of any othersuitable material. It is, however, essential that the connectionsbetween the back and sides be made of rubber, to allow of repeatedopening and closing of the book without injuring the said connection.

As appears from Fig. 1 of the drawings,

the sides 10 and 11 of the cover overlie the leaves 17 of the book, thesaid leaves, however, fitting between the flanges on the said sides,whereby they are properly protected.'

Inasmuch as the flanges are made integral with the sides of the bookcover, they ali'ord always proper protection to the leaves of the book.The notches 16 serve to facilitate opening of the book, the userinserting two of the fingers into two notches of opposite sides of thecover, thereby gripping the leavesof the book for opening the same.

That I Claim is 1. A book cover comprising a front side,

a rear side, each of said sides being pro-,

vided with a kerf in its inner face along its inner longitudinal edge,and a back made of rubber having its longitudinal edges fitted into saidkerfs.

2. A book cover comprising a front side, a rear side, each of said sidesbeing made of' rubber and provided with a kerf in its inner face alongits inner longitudinal edge, and a back made of rubber having itslongitudinal edges fitted into said kerfs and attached to said sides byvulcanizing action.

3. A book cover coniprising a front side7 a rear side, each of saidsides being provided with a kerf in its inner face along its innerlongitudinal edge, and a back made of soft rubber having itslongitudinal edges fitted into said kerfs.

l1. A book cover comprising a front side, a rear side, each of saidsides being made of rubber and provided with a kerf in its inner facealong its inner longitudinal edge, and a back made of soft rubber havingits longitudinal edges litted into said kerfs and attached to said sidesby vulcanizing action.

5. A book cover including a side having an inwardly projecting flangearound each of its free corners, said flange being innnovable inrelation to said side. i

G. A book cover including a side having an inwardly projecting flangemade integral therewith around each of its free corners, said liangebeing immovable in relation to said side.

7. A book cover according to claim said fianges being provided withnotches.
